y=100.7

y=100.7

y:0,04 + y x 3/2-y x 6,5 = 2014

y x 25 + y x 1,5 -y x 6,5=2014

y(25+1,5-6,5) =2014

20 x y=2014

Vậy y = 2014/20= 100,7

Ta có:y:0,04+y*1,5-y*6,5=2014

y*25+y*1,5-y*6,5=2014

y*(25+1,5-6,5)=2014

y*20=2014

y=2014:20

y=100,7

y/0.04+y*3/2-y*6.5=2014

=>y*(1/0.04)+y*3/2-y*6.5=2014

=>y*(1/0.04+3/2-6.5)=2014

=>y=100.7
